SUCTION CLEANER Filed Aug. l5. 1931 Patented Jan. 17, 1933 UNITED STATESPATENT OFFICE EUGENE BUTZER, 0F BASEL, SWITZERLAND, ASSIGNOR T0 THEHOOVER COMPANY, OF NORTH CANTON, OHO, A CORPORATION OF OHIO S'UCTIONCLEANER Application filed August 15, 1931. Serial No. 557,322.

This invention relates to suction cleaners and more partlcularly tg.means for resiliently supporting the upper end of the bag nor-v mallyused with suction cleaners of the porte able type. Suction cleaners areusually provided with a dust bag of cloth or similar material,detachably connected to the outlet of the body of the cleaner, andsupported at 1ts upper end by attachment to a handle whlch is pivotallyconnected to the body of the cleaner and by which the cleaner may bedirected over the surface to be cleaned. Since the point of attachmentof the lower end of the bag to the body of the cleaner is at a pointseparated from the pivotal connection between the handle and the body ofthe clener the movement of the handle toward its upper position tends tostretch the bag so that .it is necessary to provide a resilient, or

otherwise yielding, connection between the upper end of the bag and thehandle of the cleaner.

One of the objects of the invention is to provide a support for theupper end of the bag which is durable and eflicient, and which can beeconomically manufactured and vinstalled. A further object of theinvention is to provide such a supporting means which will have aminimum of protruding parts, and the movement of which will be limitedin each direction'. A still further object is amount of the extension ofsuch supporting. means. Further objects of the invention- 'and novelfeatures of the construction ywill be apparent from the, followingspecification, when considered together with the acompanying drawing, inwhich Fig. 1 is a view 1n's1de elevation of a suction cleaner embodyingthe invention;

Fig. 2 is a fragmentary view, on angenlarged scale, of the handle andsupporting means shown in Fig. 1, parts being broken away to show thestructure more clearly;

Fig. 3 is a fragmentary bottom plan view on a much enlarged scale of onedetail of construction shown in Figs. 1 and 3; and

Fig. 4 is an .enlarged cross-sectional view taken on the line 4-4 ofFig. 3.

Asshown in Fig. 1, a suction cleaner body 11, provided with a nozzle12,"and carrying a motor indicated generally at 13, is mounted uponwheels 14, and a tubular handle 15, is

rigidly secured to the socket 16 of a bail 17,

which is pivotally connectedat 18 to the body v 11, so that the cleaneras a whole may be diformed with a wide flat circular flange 23 to whicha bag ring 24, attached to the bag, is detachably secured by nuts 25 orsimilar means. The dust filtering bag 26 is preferably formed with anopen top, closed bya spring clamp 27 or other suitable means, such clamp27, or other member, being adapted to be engaged by a hook 28.

In order to provide a long spring so that the tension of the spring maybe substantially uniform regardless of the extension thereof, the longtension spring 29 is located within the hollow handle 15 and providedwith an eye- 30 at its lower end which is engaged over a tongue 31,struck up from the metal of the handle and bent down at its lower end toform a-loop as shown in Fig. 2. The upper end' of the spring 29 isformed with an eye 32 which is engaged by a'tape 33, the end of which isbent back upon itself and secured by a rivet or similar means. The tape33 extends upwardly within the tubular handle 15, and about a pulley 34,which is sef cured in an o ening 35 in the tubular handle,

Vthe hook 28 eing `secured to the upper end of the tape 33 outside ofthe handle in any suitable manner. Rivets 36 and 37 are proportionorAtab 39.,. secured upon the outside ofthe tubular handle 15 by screw 40,or similar means, and parallel lateral portions 41 and 42 which extendinto the tubular handle 15, and between which the pulley' 34 isrotatably mounted upon pintle 43. The side portions 41 and 42 arepreferably. formed with inwardly bent tabs 44, under which the tape 33is engaged so that they will act as an abutment to engage rivets 36 and37 and limit the movement of the'tape. At the lower edge of the opening35 the metal of the tubular handle 15 is preferably bent in slightly asshown at 45, and engaged within notches 46 formed in the lower edges ofthe lateral portions 41 and 42, thereby assuring that the pulley and itssupport will be rigidly held in place.

llVith the construction shown itwill be apparent that when the handle l5is raised to vertical position a tension which is substantially uniformwill be maintained upon the bag 26, the tape 33 rolling upon the pulley34 as the tension spring 29 is elongated. It is apparent that with thisconstruction a tension spring of considerable length maybe utilized, andthat the only parts of the supporting means protruding from the handleare the tape 33 and the hook 28, so that. the

\ construction presents a neat appearance.

y It will be understood that other means of support-ing the pulley 34may be usedand that other changes may be made in the sizes of parts andthe details of construction without departing from the spirit of theinvention which is defined by the following claims lVhat is'claimedis 1. In a suction cleaner, the combination of a body having an outlet,a dust bag connected to said outlet. a hollow handle pivotally engagingsaid body and having an opening therein, and means for supporting theupper end of said leg comprising a spring within and secured at one endwith respect to said hollow handle and a flexible member connected withthe other end of said spring and passing through the opening in saidhandle, said member having means at its free end for connection withsaid bag.

2. In a suction cleaner, the combination of a body having an outlet, adust bag connected to said outlet, a hollow handle pivotally engagingsaid body and having an opening therein, and means for yieldablysupporting the upper end of said bag comprising a tension spring withinand secured at one end with respect to said hollow handle, a pulleymountedadjacent the opening in said handle, and a flexible memberconnected at one endr to the other end of said spring and passing oversaid pulley and having means adjacent its other end for connection withsaid bag.

3. In a lsuction cleaner, the combination of a body having an outlet, adust bag connected to said outlet,`a handle pivotally engaging said bodyand meansfor yieldably y ing in its wall, and means for yiel ablysupporting the upper end of said bag, comprising a spring4 within andsecured at one end with respect to said hollow handle, a pulley, aflexible member connected at one end to said spring and passing oversaid pulley, said member having means at its other end for connectionwith said bag, and a pulley mounting secured to the outside of saidhandle and having a pulley-carrying portion projecting inwardly throughthe opening in the wall of said handle.
